Guangjian Technology, operating under the brand name Deptrum, is a developer of 3D vision solutions that integrate hardware and software to deliver intelligent visual perception technology for IoT applications. The company's core technologies include the Wave-Front Processor (WFP), a mass-produced consumer-grade nanophotonic chip that modulates light fields at the subwavelength scale for precise 3D perception; a Soft Core Depth Algorithm that achieves depth computation directly on embedded CPUs without DSP or ASIC, delivering a 50-fold improvement in reconstruction speed; a Modulated Time-of-Flight (mToF) solution combining light field modulation with high-precision ToF algorithms; and sToF technology enabling both structured light and ToF depth reconstruction with a single optical hardware set. Deptrum's product lineup includes the Stellar ToF Depth Camera series, Aurora Structured-Light Depth Camera series, Nebula sToF Depth Camera series, and HandPass Dual-mode Palm Recognition Camera. The company's 3D vision algorithms support functionalities including 3D Face ID, volume measurement, SLAM, image segmentation, and gesture recognition. Deptrum serves sectors including financial payments, robotics, smart cockpits, smartphones, and new retail. Founded in 2018 and headquartered in Shanghai, China, the company has raised $70.3 million in Series B funding from investors including Wu Capital, SBCVC, Green Pine Capital Partners, NLVC, CICC, and V Capital.
